Apple’s attempt to fix battery problems through its release of its iOS 5.0.1 yesterday appears to have fallen short. On the company’s Apple’s support forum, customers were complaining a lack of improvement.

 Apple Experiencing Battery Problems for iOS 5

One customer said: “I'm trying to mimic the average usage to what I use at work. I listen to podcasts for hours. Before the 5.0.0 update, I would go for about 8 hours and get from 100% to 75-85% on my 3GS. After the update, I would go from 100% to about 20% in the 3GS; big difference.”

Another customer added: “Hate to say it, but I'm registering to add to the above comments. Battery life was pretty bad on the 5.0 Worse... MUCH worse now on 5.0.1.”

A third customer expresses deep frustration: “Updated to 5.0.1 last night and my battery life seems even worse than before! My phone dropped by 4% overnight in flight mode! I have had it out of flight mode since 6.30am (at which time the battery was at 51%), and it’s now 8.30am and its down to 35%.This is with absolutely no usage - just standby on my desk! And all settings are still off, siri raise to speak, location services off, Bluetooth off, no push email etc etc."

The customer added: " I now think I'm going to have to return my iPhone and go with another brand as it's getting a bit too ridiculous now.”

 A fourth customer wrote, “After updating I thought the issue was fixed as sending 2 messages + 20 mins of music only sapped the battery by 1% (started day with 100%). Great! But then connected to Wifi and sent 8 or 9 messages and looked at BA app for a few mins and was down to 86%. Genius bar later. At least now I know it is a hardware problem.”

Many customers have been expressing similar frustrations; Apple may need to go back to the drawing board in this instance for the iOS 5 battery.
